The Mystery Cartoon Character Game, ongoing.

That could be any character at all. Can't even begin to figure it out.

Going out on a limb, since I've never actually seen the cartoon, but is it Einstein the dog from the "Back to the Future" series?

That's right! It is indeed Einstein from the Back to the Future animated series.

Just a lucky guess, I guess. Anyway, onto the next character.

1. I am my franchise's main antagonist

2. I like to do a short "song-and-dance" bit whenever I mention my full name

3. If there's one thing I can't stand, it's a certain thing my franchise's main character does

Again, I just don't have it. I'll really need to look it up.

Okay, I'm overdue for another brick. "It's sister Jenny's turn to lob the bomb / The last one, it was lobbed by brother John, brother John."

Could this be Oogie Boogie, the boogeyman from Burton's The Nightmare Before Christmas?

Nope, not Oogie Boogie. Here's the next set of clues.

4. My name is a perfect example of alliteration

5. Despite my profession, I'm quite skinny

6. I have a partner who is quite "sour"

Aha! Just found it! It's the Peculiar Purple Pieman from "Strawberry Shortcake."

Correct, Em. Definitely the Peculiar Purple Pieman of Porcupine Peak (if you want to go for the full name)

1. The Pieman is the villian in the SSC franchise

2. The Pieman has a little dance routine he does whenever he says the full name, The Peculiar Purple Pieman of Porcupine Peak ("yah-ta-ta-ta-ta-ta-ta-ta, ta-ta-ta-tah! Cha!") (it's better if you see it in the cartoon, trust me)

3. The one thing the pieman can't stand is Strawberry Shortcake's "berry talk"

4. Self-explanitory

5. The pieman is extremely skinny

6. They gave the pieman a partner in SSC's third special, and her name was Sour Grapes

You're up, Em.

Thanks, Fluidgirl. Now here's another I've wanted to post for quite some time:

1. I have an angelic name.

2. My home's in the local church.

3. Combine my name with that of the rodent I meet and befriend, and you get a guy who sings about shocking monkeys and sledgehammers.

The Peter Gabriel clue was a give-away - it's Gabriel Churchkitten, from the 1944 Noveltoon of the same name!

Good job, Pete. Once again, all clues are self-explanatory. So stop right up, and take your turn.

1) I appeared in 2 shorts before disappearing into obscurity.

2) Since it was not mentioned in the cartoons, even the proper form of my name is debatable.

3) I start off fishing, which is appropriate, and end up smithying.

I haven't a clue about this one. Someone else may have seen this guy.

Please note that I have slightly amended the wording of clues 2 & 3.

Even those amended clues don't help much. I just can't find a perfect match.

Then try these further three...

4) While nothing to do with the storyline, both films build gags around a notable feature of my species.
5) In my first film I have a goofy voice, and the plot plays out like a Warner Brothers' cartoon - which it isn't.
6) In the second film my voice not so deep, and I act a bit like Donald Duck - but it isn't a Disney cartoon.

Still can't find any that match the clues. I'm stumped but good.

I've actually got it. The character's name is Pete/Peter/Petey Pelican. I have heard of the short "The Tangled Angler" (although I have never seen it) which was directed by Frank Tashlin--however, I never knew this pelican was in a second short.

You have indeed!

The second of the Columbia Screen Gems films was "Under the Shedding Chestnut Tree, in which Pete/Peter/Petey (well put, Glowworm - various sources give these variable versions of his name!) is a blacksmith trying to shoe a horse which kicks him into a well every time a spiky chestnut drops on its rump. The film was directed by Bob Wickersham, one of several Disney staffers Tashlin hired for Columbia Screen Gems from the Disney picket line. By this time Tashlin had given up the time-consuming job of directing in order to properly oversee the running of the Screen Gems studio, but he would have had considerable input at the storyboard stage.

Casting Pete (or whatever) as an angler is appropriate - pelicans fish. "A wonderful bird is the pelican; his beak can hold more than his belican" as Dixon Lanier Merritt put it, and Tashlin makes great play of it: in The Tangled Angler Pete whistles with the air in his pouch - as it runs out his whistling falters and he has to refill; the smart-alec fish variously uses it as a pedal bin, a bath and a gondola. In Under the Shedding Chestnut Tree the frogs in the well treat it as an air-raid shelter and a street-car.

Pinto Colvig voices Pete in the first film with his "Goofy" voice. But in Under the Shedding Chestnut Tree Pete is given a higher pitch, more suitable to a bird, perhaps.

Tashlin had worked at both Schlesinger's and Disney's, of course.

Well done, Glowworm - over to you!
